When requesting assistance, please provide the complete model name and product number (p/n) of the HP computer in question. HP/Compaq makes thousands of models of computers. Without this information it may be difficult or impossible to assist you in resolving your issue.
The above requested information can be found on the bottom of your computer, inside the battery compartment or on the startup BIOS screen. Please see How Do I Find My Model Number or Product Number? for more assistance locating this information. DO NOT include your serial number. Please enter the model/product information into HP's Online Consumer Support page and post it here for our review.
1) NO, this will not work. You must use HP Recovery Discs that are specific to your computer model. You may be able to purchase HP Recovery Discs from HP or a third party vendor.
2) A 1TB drive may work, however you need to make sure it will fit in the computer before purchasing it. You may be better off with a 2,5" 500GB drive.
3) You need to remove the drive from your laptop and place it into a external USB 2.5" SATA hard enclosure. Next, connect the enclosure to another computer and try to read the data from it.
If you have any further questions, please don't hesitate to ask.
